The splitMultiple function takes a string and an array of separators as parameters and splits the string into an array on each occurrence of a separator. We used the same approach in the function: Replace all occurrences of the separators with a unified character (a dollar sign). Split the...
To split a string into an array of characters, specify an empty string ("") as a separator.ExampleTry this code » let str = "INTERSTELLAR"; let strArr = str.split(""); document.write(strArr[0]); // Prints: I document.write(strArr[1]); // Prints: N document.write(strArr[...
let primes = [2, 3, 5, 7]; // An array of 4 values, delimited with [ and ]. primes[0] // => 2: the first element (index 0) of the array. primes.length // => 4: how many elements in the array. primes[primes.length-1] // => 7: the last element of the array. prim...

split() Break a string into an array of substrings. Example 1: Regular Expressions const string = 'Find me'; const pattern = /me/; // search if the pattern is in string variable const result1 = string.search(pattern); console.log(result1); // 5 // replace the character with anothe...
